DRINKING WATER CASE STUDIES AND WHITE PAPERS

• Rural North Texas Community Cuts Non-Revenue Water By 42% With Pipeline Leak Detection Technology

  Discover how a city solved its non-revenue water challenge by rapidly pinpointing three hard-to-find leaks in 13 miles of aging pipeline using a free-swimming acoustic tool.

• Custom Water Panel Answers Multiple Water Questions

  A mid-size water system in the southeast was looking to pull together multiple measurements in a single panel. After reviewing off-the-shelf solutions, they realized there was nothing that met their requirements.

• Battling Biofilm

  Biofilms are extremely complex ecosystems that provide excellent protection for the microorganisms within. This often makes them difficult to kill, even with chlorine. Basic understanding of biofilm ecosystems and their behavior to chlorine and other oxidizing biocides can offer valuable insight into achieving better microbial control. 

• Standards For Testing And Certifying Cured-In-Place Pipe

  It is estimated that nearly 75,000 miles of wastewater and water pipelines have been lined with Cured-In-Place Pipe (CIPP), with nearly $3 billion spent annually on the trenchless renovation method, worldwide. Recognizing the growing use of CIPP and inability of CCTV inspection to accurately or consistently certify trenchless rehabilitation as defect-free, this paper chronicles the emergence of new guidelines to test, certify, and accept CIPP lining projects, using Focused Electrode Leak Location (FELL) inspection.

• Why Does Copper Contamination Cause A Risk To Community Health? And How Can It Be Tackled?

  The human body needs small quantities of copper to function. But as well as being a nutrient, copper can also be harmful if consumed in large quantities.

• Why Static Metrology Is Important In A Modern Era

  As sustainability, climate change resilience, and the overall increasing cost of water increasing come into focus, the needs of water utilities and their customers have shifted.

• How Valve Insertion Can Underpin Sustainability

  To save money and protect the environment, municipal water systems are increasingly under pressure to adopt sustainable practices. However, progress in this area is often hampered by a wide array of issues. As an alternative to traditional valves, the use of valve insertions has emerged as a sustainable maintenance solution.

• How Biogrowth Can Aid In Disinfection Byproduct Removal

  Learn how naturally occurring biological growth on carbon media can help enhance removal of total organic carbon (TOC) and thusly reduce the formation of DBPs.

• Innovative Communication Tool Enables Robust And Contact-Free Control Capabilities

  Two-way wireless communication can provide a wealth of benefits for municipal water utilities, including command and control abilities that underpin a wider smart city infrastructure. However, most tools currently on the market do not provide the flexibility and uncompromising speed that are necessary to enable these capabilities. The newly released Mueller® Mi.Net® LoRaWAN® (LW) node, by comparison, allows two-way data communication to take place within seconds instead of hours.

• Constructing A Winding Box Culvert Channel In A Steep, Rocky Canyon

  Special precast box culverts were used for one of the most significant segments of the $25.8 million emergency water restoration project, designated by the NRCS, known as the Cache Water Restoration Project (CWRP). The CWRP project involved the reconstruction and improvement of approximately six miles of mostly open, unlined channels that make up the Logan and Northern, as well as the Hyde Park and Smithfield canals. The project incorporated new precast pipeline, box culverts, a section of pressurized pipe, metering systems, turn-outs, head gates, and improved maintenance access.
